In spite of having higher carrier mobilities and absorption coefficients germanium (Ge) than those silicon (Si), there has been less focus on Ge-based solar cells due to the low bandgap high-cost Ge wafer as well requirement its high-purity level. Currently, availability (HPGe), low-cost slicing method proper design guidelines make it possible HPGe-based cells. Accordingly, in this article, we ...

The beam energy measurement system is significant and profit for both BES-III detector and BEPC-II accelerator. The detection of the high energy scattering photons is realized by virtue of the Compton backscattering principle. Many advanced techniques and precise instruments are employed to acquire the highly accurate measurement of positron/electron beam energy. During five years’ running peri...

Fingerprinting excited nuclear states by γ-ray spectroscopy has been a viable tool to benchmark nuclear models for decades. Since contemporay nuclear structure investigations aim at the study and understanding of very exotic nuclei at the limits of stability and their decay properties, large and thus highly efficient γ-ray spectroscopy instruments are the basis for continued discoveries into th...

We have measured the fraction of bb events in hadronic 2’ decays, R,g, using the vertex detector system of the Mark II detector at the SLC. We tag bb events by requiring the coincidence of three or more tracks with significant impact parameters. This tag is 50% efficient and results in a sample of 85% purity. We find R,b = 0.251 f 0.049 f 0.030, in good agreement with other measurements and the...

GENIUS is a proposal for a large volume detector to search for rare events. An array of 40–400 ’naked’ HPGe detectors will be operated in a tank filled with ultrapure liquid nitrogen. After a description of performed technical studies of detector operation in liquid nitrogen and of Monte Carlo simulations of expected background components, the potential of GENIUS for detecting WIMP dark matter,...

This paper presents grammatical evolution (GE) as an approach to select and combine features for detecting epileptic oscillations within clinical intracranial electroencephalogram (iEEG) recordings of patients with epilepsy. Clinical iEEG is used in preoperative evaluations of a patient who may have surgery to treat epileptic seizures. Literature suggests that pathological oscillations may indi...

Several different vertex detector designs for the Linear Collider Detector (LCD) are evaluated in the context of measurements of the branching ratio of the standard model Higgs particle decaying into charm/anti-charm final states. Fast Monte Carlo simulations are used to model the detector and neural network-optimized flavor tagging is used to perform the measurements. These tools are used to s...

K-shell fluorescence yields of low, medium Z and rare earth elements were determined using Si(PIN) detector and HPGe detector employing reflection geometry set up. Target atoms were excited using 59.5 keV gamma rays emerging from Am-241 source of strength 300 mCi. Background radiation and multiple scattering effects were minimized by properly shielding the detector. The elemental foils of unifo...

Gentiana lutea is a herbal bitter drug that is used to enhance gastrointestinal motility and secretion. Recently we have shown that amarogentin, a characteristic bitter compound of Gentiana lutea extract (GE), binds to the bitter taste receptors TAS2R1 and TAS2R38 in human keratinocytes, and stimulates the synthesis of epidermal barrier proteins. Here, we wondered if GE also modulates lipid syn...
